func ParseISO8601

func ParseISO8601(from string) (Duration, error)

ParseISO8601 parses an ISO8601 duration as well as some Rill-specific extensions. (Section 3.7 of the standard supposedly allows extensions that do not interfere with the standard.) Current extensions are, 1. "inf" for representing an unbounded duration of time 2. X-To-Date and Previous-X duration supports with a prefix of "rill-" to DAX notations.
